In its natural state cellulose is not usually suitable for utilization as an emulsifier because it forms strong intermolecular hydrogen bonds, which make it insoluble in water. Nevertheless, it can be isolated and modified in a number of ways to produce food-grade ingredients that have interfacial activity and can be used as emulsifiers [107]. The most commonly used surface-active cellulose derivatives are methyl cellulose (MC), hydrox-ypropyl cellulose (HPC), and methyl hydroxypropyl cellulose (MHPC). These ingredients...

Cellulose ethers, more particularly methyl cellulose (MQ, methylhydroxypro-pyl cellulose (MHPC) and hydroxypropyl cellulose (HPC) are used as protective colloids also called primary suspending agents in suspension polymerization for the manufacturing of S-PVC. Their role is maintaining the particle size of the resin. Hydroxyethyl cellulose (HEC) is preferred for manufacturing of vinyl acetate emulsion polymers and as a thickening agent in dispersimi paints.
